I have a B16 motor and was curious if having an I/H/E would really make a difference if your motor is completely stock.

Just trying to save money i suppose. Only thing i have so far is an intake. Wanting to get a Greddy Evo2 exhaust but i'm unsure of how much i should even spend on a header.

Thanks. :D

 

Basic bolt-ons are like pissing your pants - they make you feel warm and fuzzy, but no one else actually cares. There's no real benefit.

 

Very insignificant gains with bolt ons. You would be lucky to increase your hp by 10-15 tops and that is being optimistic. A intake will help your throttle response more than anything IMO.

 

Nope.

 

Makes sense, thanks guys.

With that said, regardless i need to replace my exhaust manifold and exhaust because i have cracks on them.

Aside from the Evo2 that i plan on installing, can you guide me on how much i should spend on a header? For example, whether it be something like DC or even eBay header. My exhaust manifold needs to be replaced regardless.

 

Like they said, very minimal gains with a 4 banger. There's dyno's somewhere along testing the best of the best I/H/E setups and they don't gain much.
Boost it
As far as your header problem. People say to stay away from eBay headers. I bought one for my D16 (back in my ignorant days) but it lined up perfectly. Never had a problem with it. Only $50 too! Maybe I just got lucky, who knows. If you wanna play it safe you could buy a DC header or a name brand, but they're expensive. Depends what you wanna do I guess. Are you planning on building it at all now? High comp? Boost build?

 

Eh, I've used two different off-brand headers on my car now, and two of my friends have also used them on their cars. We've never had cracking problems. Just make sure you install them correctly, with the proper spring bolts.

 

Damn you got lucky then eh. Hah.

Tbh, as of right now, I want to keep the internals as stock as possible. I wanted to keep it all stock all around but once I had my exhaust problem, I decided why not, upgrade the bolt-ons. Right now I have a PLM Toda Style Header in my garage but I don't know if I even want to install them because some people are telling me it's a waste of money if I'm all stock ya know? Might plan on selling it and just getting what you or some others might recommend what's best for what I need now.

 

Off brands like eBay?

 

eBay isn't a brand. eBay is where people sell and buy stuff. Off brand just means "not name brand", I.E. cheap on eBay.

 

Apologies. I meant to say brands you are able to purchase from through the help of eBay.

 

You can buy almost anything through eBay, even high quality name brand parts.

 

Yeah thanks bro.

As of right now, a DC Header may be on my to buy list but i'm going to do more research and see what's my best bet so i don't have to flush my wallet on a header that will be useless.

 

Use what ya got. I love my PLM hytech header coupled with my Yonaka WS-II replica exhaust. Unless you find a dc header for free, I wouldnt bother.

 

Sounds good my man.

 

it made a huge difference on the older Honda stuff, mainly because the exhaust systems on them were horribly restrictive, also the older ones respond well to a cam change, if you want to make power on anything newer, you not only would do what you've done, but the car will have to be tuned to take advantage of it, i'm into old school carbed stuff, do they still swap cams today? Honda gets a lot more power out of them then they used to, so there isnt as much to work with, the older cars had the potential to make power, but were strangled with old style emissions

 

How old is old?

 

I bought a header off of dnamotoring.com for my si. fits great and I haven't had a problem with it. cost me 70 bucks with free shipping

 

YET!!! $70 couldn't even pay for quality piping to make my own.

 

I think I paid 250 for the S&S but that was through a private seller who had never taken it out of the box, good deal for a rare long tube header

 

For some reason I would have to agree with everyone on this one when it comes to off brand headers for cars. But for some reason it seems to skip on Hondas LOL. On any other car off brand headers are a nightmare to install. But I've have had good luck on my Honda's. Tbh if you don't plan on doing much to your car but want to upgrade the exhaust I see really no reason you shouldn't just go ahead and buy a whole system off brand. They're usually not THAT bad and they're really cheap but most are loud as ***** sadly.

 

yes I went cheap but that's only because I plan on doing a turbo build this summer and the flame where my down pipe connects too my cat its rusted and its literally falling apart. I'm not going to spend a lot of money on an expensive header if it's just going to be replaced in a couple months anyway. besides on a stock motor like the op has and plans on keeping power gains with an expensive header aren't going to be very different from a cheap one.

 

Op- if you want to see actual bolt-on dyno tests on nearly stock b16- import tuning magazine, power pages section. @doctorake and the like- I'm not at all saying that I support a specific brand because of a magazine. Nor do I believe a specific part gives spec gain. If anything, I'm recommending power pages for "ballpark" gains on parts similar in design to ones tested in mag...

 

if you add something like a header, you need to make sure air can get into the engine better, as well as through the head, then you have to tune for it, whats the point of letting exhaust leave the engine faster if air cant get into the engine or through the head faster? this means intake system, cam, head work, tuning to allow the ECU to use that additional airflow, and a header with proper sized exhaust, bigger doesn't always mean better, if you go oversized then you lose scavenging ability and can hurt power, the only exception to this rule is with a turbo, which is completely different as far as exhaust requirements

 

OP, read this thread. It was written by people who have nothing to gain from the truth that bolt-ons on these motors do not do very much if anything(magazines get revenue from ads for these products that do not do anything, they want you to buy them).
